SYNCHRONIZATION OF ULTRAVIOLET-PREIONIZATION IN A MARX-DRIVEN TEA CO2 LASER

摘要

In a TEA CO2 laser a two-stage spark gap was used to control the predischarge, which produced the ultraviolet-preionization, and to generate a trigger pulse for the Marx bank, which excited the main discharge. The time-sequence of the predischarge and the trigger pulse could be reversed so that the main discharge could commence before the preionization process, This set-up has enabled temporal synchronization on the laser performance, or basically the time delay between the pre- and the main discharges, to be investigated from about -150 ns to 600 ns.
